Spicy Honey Mongolian Beef

Why This Spicy Honey Mongolian Beef Works

As the steak sits in cornstarch, a light coating forms on the outside. In the hot oil, that coating grabs onto the surface and browns fast. The outside becomes a little crisp while the inside of the thin slices stays tender, instead of drying out. When the steak comes out of the pan for a bit, that crust also keeps the juices inside so it doesn’t overcook while the rest of the pan is working.

While the garlic, ginger, bell pepper, and green onions cook, they soften and lose their raw bite. Once the soy sauce, honey, chili garlic sauce, and water go in, the liquid is pretty thin at first. As it heats and bubbles, the honey thickens and the cornstarch left in the pan from the steak starts to swell. The sauce slowly turns glossy and clings to the vegetables. When the steak goes back in, that sticky sauce coats every piece, so the meat stays moist and the sweet heat from the honey and chili spreads evenly through the whole pan.

Mistakes To Avoid

Cutting the flank steak with the grain or in thick strips makes the meat tough and chewy. The fibers stay long and don’t break down in the quick cook time, so instead of tender slices, the beef ends up stringy and hard to bite through.

Letting the steak sit too long in the cornstarch before cooking can turn the coating pasty. The cornstarch pulls out moisture and forms a gummy layer, so the beef doesn’t sear well and the pieces steam in the pan instead of getting a crisp edge.

Crowding the pan with too much steak at once causes the meat to release liquid and boil. The strips stay gray and soft, and there is no browned surface for the sauce to cling to, so the final dish tastes flat and the sauce feels thin on the meat.

Pouring the sauce in and then walking away on high heat often leads to a burnt, sticky mess. The honey and cornstarch thicken fast; the sauce can catch on the bottom of the pan, turning bitter and leaving the beef coated in uneven, clumpy glaze.
